Dynamic user control system

ABSTRACT

A wall controller is provided. The wall controller includes a projection screen having an input device and a projector, wherein the projector has an optical axis that is non-orthogonal to the projection screen. The wall controller includes a housing having the projector at an end of the housing. The housing is dimensioned to fit the end of the housing through an aperture in a first wall, fit the end into a wall space between the first wall and a second wall, and fit a majority of another end of the housing into the aperture until the projection screen is parallel to a surface of the first wall and a front portion of the projection screen is flush with, recessed in or extends from the surface of the first wall.

BACKGROUND

Wall controllers, for diverse devices and control of functions such asthermostats, hot water heaters, air-conditioning, ventilation, lighting,burglar alarms, electrochromic windows, intercoms, electric gates, etc.,are available in many sizes, shapes and appearances. A typical wallcontroller or other controller, interface or user interface platformmounts to a wall, partition or other surface of a home, office, factoryor other building, and communicates wirelessly or through wires (withinor attached to a wall) to devices controlled by the wall controller.Functionality, features, design aesthetics and available space arefactors in the design of a wall controller. A wall controller thatmounts entirely to, and not within, a wall may appear bulky andutilitarian, and be limited in features by available size of the wallcontroller and wall space allocated to the wall controller. Controllersalso have an impact on the design of a home. Devices hanging obtrusivelyon a wall pull attention away from architecture itself and towards thedevice. Subtlety of added elements in a high-end home environment isimportant for respect of the environment. Installation constraintsimposed by wall spacing (e.g., inner wall space) and the desire tominimize the number and size of holes or other visible alterations madeto or in the wall, and complexity of installation may serve as barriersto the ability to add further features to wall controllers. It is withinthis and further design contexts that the present embodiments arise.

DETAILED DESCRIPTION

A dynamic user control system for use in lighting or energy controlsystems is described herein. The light control or energy control systemsmay include smart windows that are devices such as windows or doorshaving a computer processor and/or connectivity to the internet. In someembodiments the smart windows may be electrochromic devices. Othersystems such as lights, non-electrochromic windows and doors, HVACsystems, or cooling or heating systems may also be part of the lightingor energy control systems. Embodiments of the dynamic user controlsystem provide a user to interact with and control the lighting orenergy control systems. The dynamic user control system may include userinput devices such as a wall controller, various types of wall switches,a user app on a mobile device, or a voice control device. The dynamicuser control system may be augmented by one or more sensors. The userinput devices of this dynamic user control system may be able tocommunicate directly with a smart window through wired or wirelesscommunications, and may also be able to communicate with a smart windowthrough the internet or through a local area network. In one embodimenta user input device or multiple user input devices of the dynamic usercontrol system may communicate with the electrical drivers of a smartwindow using a wireless mesh network. In another embodiment a user inputdevice or multiple user input devices of the dynamic user control systemmay communicate with the electrical drivers of a smart window though alocal gateway device that passes the communications through a cloudnetwork or the internet.

In an embodiment of the present invention, a user input device of thedynamic user control system or of any user control system may be a wallcontroller. The wall controller described herein may be for mounting toa wall and control of household, office, industrial or other systems,and has a rotatable rear projection touchscreen for manual input andvisible output. A message or animation projected from a projector hiddenin the wall onto the rear projection screen stays level (i.e., at afixed orientation) relative to the wall for viewing even while a frontscreen, on which the image is visible, is rotated by a user finger forinput. Arrangement of the components and dimensions of the housingpurposefully support installation through a hole in the wall, sized tofit the viewable, rotatable face of the wall controller, with thebackside components of the wall controller, inside the housing, fittingin the wall space between two walls. Some embodiments feature a glow oranimation projected onto the wall, surrounding the rotatabletouchscreen, and/or images or animation projected onto an opposing wall.

In some embodiment, a wall controller is provided. The wall controllerincludes a housing, dimensioned to insert into an aperture in a wall andmount to the wall with a majority of the housing behind a front surfaceof the wall. The wall controller includes a transparent or translucenttouch film mounted in fixed relation to the housing and a transparent ortranslucent rotatable viewscreen in rotatable relation to the housing,in front of and overlapping the transparent or translucent touch film.The wall controller includes electronic and optical components mountedto the housing to show an image visible on or through the transparent ortranslucent rotatable viewscreen and sense, via the transparent ortranslucent touch film, position or movement of one or more fingers onor near the transparent or translucent rotatable viewscreen. The wallcontroller can receive audio commands and interpret the audio commandsto distribute instructions to electrochromic devices in someembodiments. A wall switch may also receive audio commands anddistribute or interpret the commands to transmit the commands orinstructions to other wall switches or to electrochromic devices.

FIG. 1A is a front view of a wall controller 102 in accordance with thepresent disclosure, mounted to a wall 106 and showing a message 110and/or animation 112 on a rotatable screen 108 while also projecting aglow 116 or image onto the wall 106. A finger 118 of a user is showntouching a textured outer region 114 of the rotatable screen 108, torotate the rotatable screen 108. The textured outer region 114 couldhave micro texture, macro texture, or be of a different finish, materialor paint than an inner region of the rotatable screen 108, so as to havea grippy effect on a finger. Touching outer region 114 could increase ordecrease a setting in a device controlled by the wall controller 102,which could be accompanied by a message 110 or animation 112 displayedon the rotatable screen in response to such input in some embodiments. Auser can also tap a finger 118 on the rotatable screen 108 or move orslide a finger 118 along the rotatable screen 108, which can detect allsuch finger touches or movement. In some embodiments, an inner region,i.e. inside of the textured region 114, of the rotatable screen 108 issmooth to suggest to the user that finger taps or slides are appropriatein this inner region, and to allow one or multiple finger sliding. Thismay include a matte finish as opposed to a glossy surface, althoughvarious surface finishes or textures could be appropriate. Texturing inthe textured outer region 114 could be bumps, ridges, roughness, a wavysurface, a series of concentric raised circles around the rim, geometricshapes, crosshatching, or other deviation from a smooth flat surface tosuggest to the user that finger placement for rotation of the rotatablescreen 108 is appropriate in this textured outer region 114. However,further embodiments are smooth or textured across the entirety of therotatable screen 108 and rely on visual cues for finger placement of theuser. Variations of this, with some textured regions and some smoothregions, are readily devised. Visual cues could also be applied byprojected image, and appear only when appropriate to a control, mood orother scenario.

A majority or the entirety of the housing 104 is inside the wall 106 asillustrated in FIG. 1A, or more specifically in the wall space betweenthe wall 106 and another wall or surface. In various embodiments, therotatable screen 108 is flush with the front surface of the wall 106(e.g., embodiments without the projected glow 116 onto the wall 106), oris raised slightly from the front surface of the wall 106 (e.g.,embodiments with the projected glow 116 onto the wall 106). FIGS. 1B and1C illustrate various embodiments with examples of user interfacesillustrated on the rotatable screen 108. It should be appreciated thatvarious user modes and sub-menus within the different modes may beemployed based on the application as FIGS. 1A and 1B are examples andnot meant to be limiting.

FIG. 2 is a cutaway side view of the wall controller 102 of FIG. 1A,depicting a portion of an image projected from a projector 208 onto arear projection screen 204, and a further portion of the image reflectedoutward and backward by a shaped, reflective rim 210 surrounding therear projection screen 204. The rear projection screen 204 and arotatable front screen 202, together form the rotatable screen 108.These components of the rotatable screen 108 are mounted to a first end228 of the housing 104. This is accomplished, in the embodiment shown,with a bearing 212, for example a ring bearing, rotatably coupling therotatable front screen 202 and the rear projection screen 204, which isattached to a first end 238 of the housing 104. The reflective rim 210(i.e., a reflective outer edge) is attached to or at the boundary of therotatable front screen 202 and surrounds a boundary of the rearprojection screen 204. A projector 208, which could also be termed arear projector since it projects onto the rear projection screen 204, ismounted internal to a second end 230 of the housing 104. A controller234, or more than one controller, could be mounted in various locationsin the housing 104, outside the housing, in a second housing orintegrated into the projector 208, in various embodiments. Thecontroller 234 interprets user input for the wall controller 102 anddevelops output, in the form of digital images or animation to beprojected by the projector 208. In the embodiment shown, a mirror 206 ismounted to a middle section 232 of the housing 104. Selection ofmounting arrangement for the projector 208, and use of and mountingarrangement for the mirror 206, are driven by design objectives. Theseobjectives include using a rear projected image with sufficient lengthbeam path to allow for expansion of the beam and a full-size image onthe rotatable screen 108, and fitting the housing into a standard wallspace for ease of installation and attractive appearance of the wallcontroller 102. Off-axis projection, without the mirror 206, could alsobe used for placement of the projector 208 in a further embodiment. Inreflected-beam and off-axis projection versions, the projector is otherthan on a line perpendicular to the rear projection screen. That is,projector 208 has an optical axis that is non-orthogonal to rearprojection screen 204 and rotatable front screen 202. In still furtherembodiments, lenses or combinations of lenses and mirrors could be usedfor various folded and or lensed beam paths and other housingarrangements. A projector with sufficiently wide beam or rapid beamexpansion may be employed, or a system of lenses achieves this, toenable use of a direct, on-axis projection arrangement.

In one embodiment, the overall depth 220 of the housing 104 is less thanor equal to four inches, so that the housing 104 of the wall controller102 fits into a wall space between standard-spaced walls in a home orcommercial building, as shown in FIG. 3. The shape of the housing 104,and overall length 222 of the housing 104 are also dimensioned to sofit, and in some embodiments the overall length 222 of the housing 104can be greater than the overall depth 220 of the housing 104, toaccommodate a beam path from the projector 208 to do the rear projectionscreen 204.

In the embodiment depicted in FIG. 2, a majority of the image from theprojector 206 reflects off of the mirror and is rear-projected onto therear projection screen 204 and/or the rotatable front screen 202. Thatis, in various embodiments, the image is projected onto a translucentrear projection screen 204 and is visible through a transparent (ortranslucent) rotatable front screen 202, or is projected through atransparent (or translucent) rear projection screen 204 and is visibleas projected onto a translucent rotatable front screen 202, or isvisible on both the rear projection screen 204 and the rotatable frontscreen 202. Preferably, one or the other of the rear projection screen204 and the rotatable front screen 202 is transparent, and the other istranslucent. Translucency can be produced by using an opaque substratewith holes, such as a mesh or a grill, or by tinting transparentmaterial, thinning opaque material, using a textile, mesh, grill,diffusion film, etc. In further embodiments, other optical componentscould be applied to produce an image.

This projection is shown in FIG. 2 with the center ray 216 of theprojected image, and is seen from the front of the wall controller 102as the full-screen message 110 (see FIG. 1A) and/or animation 112. Sincethe projector 208 and mirror 206 are in fixed arrangement with thehousing 104, the projected image stays in fixed orientation relative tothese components and the wall 106 to which the wall controller 102 ismounted, even as the rotatable front screen 202 is rotated. Moreover, insome embodiments the projected image extends far enough laterally tofill the rear projection screen 204 and/or the rotatable front screen202, all the way to the edges. In some embodiments, for a framelessscreen result, a light piping effect in the rotatable front screen 202could be applied to lighten shaded areas. In some embodiments, theprojector 208 is directed, for example by a controller, to rotate theprojected image to match rotation of the rotatable front screen 202. Forexample, one or more arrows or other symbols could be shown moving withrotation of the rotatable front screen 202, in the projected image.

In some embodiments, and as shown in FIG. 2, the projected image isgreater in extent than the rear projection screen 204 and the rotatablefront screen 202, as depicted with the outer rays 214, 218. A portion ofthe projected image, e.g. these outer rays 214, 218, escapes through atransparent or translucent portion, or an opening such as a hole, windowor absence of material, of the housing 104, a transparent or translucentportion of a skirt or other support of the rear projection screen 204, agap between the housing and the rear projection screen 204, or someother window or transparent or translucent area, and reflects outwardsand backwards off of the shaped, reflective rim 210 or outer edge of therotatable screen 108. In a further embodiment, light escapes straightout to project on outside elements or an opposite wall, etc. When thewall controller 102 is mounted to a wall 106, as shown in FIGS. 1 and 3,this outer reflected image appears as the glow 116 on the wall 106. Inthe embodiment shown, the shaped reflective rim 210 is a radiallysymmetric skirt or other extension rearward of the rotatable frontscreen 202, and could be painted, plated, or polished for betterreflectivity. In various embodiments, the shaped reflective rim 210 iscurvilinear, an angled flat surface, multiple angled flat surfaces, or acombination of curved and flat surfaces, for even or graduated lightdistribution, or could be faceted, ringed, wavy or textured for variousreflective effects, etc. In further embodiments, the shaped reflectiverim 210 is a skirt or other extension rearward of, aligned with or infront of the rear projection screen 204. Thus, the shaped reflective rim210 allows for light from the outer rays 214 and 218 to appear toemanate from the wall region external and proximate to the periphery ofthe housing 104. This light may be referred to as a glow in someembodiments, or may be an image in further embodiments. In someembodiments, the shape is designed to allow a projection closer to thewall interface, or farther from the wall interface, such that, forexample it could project elements going away from or towards the device,or a circle around the device, that would expand and contract, e.g. acircle going from one diameter to another diameter.

Depending on optical characteristics of the rear projection screen 204and rotatable front screen 202, for example a transparent region, somelight (e.g., rays 224, 226) could cast an image or a glow on an oppositewall to the wall 106 on which the wall controller 102 is mounted, insome embodiments. This could be useful for mood lighting, or in anemergency, for example to cast a bright red glow, message, image of anarrow pointing to an exit, or a circle oriented to an exit, on theopposite wall.

FIGS. 3A-C illustrate an action sequence showing installation of thewall controller 102 of FIGS. 1 and 2. An aperture 302 is made in thewall 106, for example by a user, carpenter or installation technician.Generally, the aperture 302 should be circular and dimensioned to fitthe first end 228 of the housing 104 and/or some or all of the rotatablescreen 108, or optional mounting hardware, although further embodimentscould use other shapes such as an oval or a rectangle, and correspondingcross-sections of the housing 104. The second end 230 of the housing 104of the wall controller 102 is inserted through the aperture 302 and intothe wall space 306 between the wall 106 and a further wall 304. Thesecond end 230 of the housing 104 is then rotated into the wall space306, downward in this embodiment but the rotation could be sideward orupward in further embodiments. As the downward (or sideward or upward)rotation of the second end 230 of the housing 104 completes, the firstend 228 of the housing 104 seats in the aperture 302 in the wall 106,with the majority of the housing 104 in the wall space 306, and therotatable screen 108 facing outward from the wall 106. The rotatablescreen 108 is then flush with the wall 106 (e.g., in some embodimentslacking the reflective rim 210) or nearly flush with the wall 106 (e.g.,in embodiments that have the shaped, reflective rim 210 and cast theglow 116 as illustrated in FIGS. 1 and 2). In some embodiments, thesecond end 230 of housing 104 has a periscope configuration where thesecond end 230 can extend downward through a periscope mechanism oncethe controller is situated in place in FIG. 3C. In further embodiments,the housing 104 could fold or unfold into the wall space 306 between thewall 106 and the further wall 304, or extend using a telescoping action.One or more portions of the housing 104 could pivot or hinge relative toanother portion of the housing 104, or otherwise deploy into the wallspace 306 between the wall 106 and the further wall 304. In someembodiments the wall controller includes the ability to tune theprojector once assembled. For example, set screws on a surface of thewall controller may be utilized to adjust the projector to provide forfine tuning the alignment after assembly. In some embodiments 3 setscrews may provide for alignment in the x, y, and z directions with oneset screw dedicated to each direction. In some embodiments, as lightsensor proximate to the projector may be utilized to adjust displaybrightness based on the brightness/light level sensed in the room.

FIG. 4 is a close-up perspective cutaway view with details of portionsof a rotatable front screen 202, a capacitive sensing film 408, a rearprojection screen 204, a bearing 212, a base ring 402, a lock ring 404and a housing 104 in an embodiment of the wall controller 102 of FIGS.1-3. To support rotation of the rotatable front screen 202, the bearing212 couples the cylindrical rim 414 of the rotatable front screen 202 tothe cylindrical rim 412 of the rear projection screen 204. In thisembodiment, the bearing 212 is a ring of one, two or more pieces made ofTeflon™ or nylon or other slippery or low friction plastic material,with the bearing 212 and both cylindrical rims 412, 414 concentric abouta rotation axis of the rotatable front screen 202. Other types ofbearings positioned below or behind the rotatable front screen 202 arereadily devised. For example, the bearing could attach to the housing104 and/or the rear projection screen 204, and further variants forinstallation other than the lock ring 404 and the base ring 402 could bedevised. One of the cylindrical rims 414 could be integral with therotatable front screen 202, and further variants are readily devised inkeeping with the teachings herein. In some embodiments, a portion ofcylindrical rim 414 has a retention device, such as a bump or bumps, toengage with a corresponding depression or edge of bearing 212, surfaceof base ring 402, surface of cylindrical rim 412, or a surface ofhousing 104, etc.

Still referring to FIG. 4., the rotatable front screen 202, in thisembodiment a circular disk, has a larger diameter or greater extent thanthe rear projection screen 204, so that the rotatable front screen 202overlaps the rear projection screen 204. Likewise, the cylindrical rim414 of the rotatable front screen 202 has a larger diameter than, andsurrounds, the cylindrical rim 412 of the rear projection screen 204. Inthis embodiment, the rear projection screen 204 and associatedcylindrical rim 412 are nested inside of the rotatable front screen 202and the associated cylindrical rim 414. Since the two screens 202, 204,and the associated two cylindrical rims 414, 412 are coupled together bythe bearing 212 and/or through assembly of further components includingthe housing 104, the rotatable front screen 202 is supported to rotaterelative to the rear projection screen 204. The cylindrical rim 412 ofthe rear projection screen 204 is attached to the housing 104, at thefirst end 228 of the housing 104. This attaches the entirety of therotatable screen 108 assembly, as a rotatable rear projectiontouchscreen, to the housing 104.

A transparent or translucent, capacitive sensing film 408 of FIG. 4, orother touch sensing film or device in various embodiments, is attachedto a front (or in some embodiments, rear) of the rear projection screen204, making this a rear projection touchscreen or clear sensing layerthrough which a projected image passes, and tuned (e.g., usingelectronic circuitry and/or the controller 234 in FIG. 2)) to sense afinger 118 (see FIG. 1) on the rotatable front screen 202. In someembodiments, the capacitive sensing film 408 is inside the rearprojection screen 204, e.g., inside the disc, for example by layering,buildup, lamination, deposition, in-mold decoration or in-mold-labelingprocess. The capacitive sensing film 408 can sense the finger 118through the thickness of the rotatable front screen 202, and can evensense the finger 118 at an edge of the rotatable front screen 202extending past an edge of the rear projection screen 204 and associatededge of the capacitive sensing film 408, or even a finger 118 near butnot touching, in some embodiments. With such sensitivity, the capacitivesensing film 408 can sense a finger touch, a finger slide, or fingermovement to rotate the rotatable front screen 202. In this embodiment,this is the sole mechanism by which rotation of the rotatable frontscreen 202 is detected. That is, there may be no optical or magneticencoders, no camera detection of finger position, and no mechanicalcoupling to gears or a shaft to a mechanical or electromechanicalencoder, etc., although these could be used in other embodiments.Associated electronics, for example in a controller 234 (see FIG. 2),interpret the capacitive sensing film 408 signal(s) to determine inputfrom a user as above, and may also develop control signals for whicheverdevice(s) the wall controller 104 is controlling or otherwiseinteracting with, or communicate signals to another controller that doesso. In some embodiments capacitive sensing film 408 is a transparent ortranslucent film.

To manage the light path for the portion of the digital image that getsreflected by the shaped, reflective rim 210, some embodiments of therotatable front screen 202 have a step feature 416 on the cylindricalrim 414 of the rotatable front screen 202, which lets light from thatportion of the digital image through to the reflective rim 210. Thiscould also be accomplished using spokes and gaps, or other shapes in atransparent or translucent material. Also, some embodiments have a lightpipe 410 in part of the cylindrical rim 414, for example behind theshaped, reflective rim 210, or forward of the shaped, reflective rim 210up to the rotatable front screen 202. Light pipe 410 allows the visiblepart of the cylindrical rim 414 to have a glow surrounding or adjacentto the rotatable front screen 202. Light pipe 410 is configured toenable light entering one region of the light pipe to be emitted atanother region, e.g., toward a surface of reflective rim 210, to givethe appearance of a glow rim around the periphery of front of frontscreen 202. In some embodiments, a reflective surface on the reflectiverim 210 creates a shadow along the periphery of the rotatable frontscreen 202. Because light projected to the rotatable front screen 202 isblocked in that shadow area, the light pipe 410 brings light to thesurface of the rotatable front screen 202 where regular projectioncannot go, so that all of the surface of the rotatable front screen 202is lit.

Referring to FIGS. 3 and 4, for ease of installation and professional orhigh-end appearance, some embodiments of the wall controller 102 haveinstallation pieces, examples of which are shown in FIG. 4. A base ring402, or in some embodiments a first base ring 402 and a second base ring406, are pieces that can be installed to the aperture 302 in the wall106, e.g., by press fit or with fasteners, fillets or adhesives. Inorder for the pieces to work in the assembly procedure shown in FIG. 3,the first base ring 402 may be dimensioned so that the second end 230 ofthe housing 104 fits through the first base ring 402 and the first end228 of the housing 104 fits into the first base ring 402. After thehousing 104 is inserted through the aperture 302, as described withreference to FIG. 3, and the rotatable screen 108 assembly is properlyaligned flush or nearly flush with the wall 108 (depending uponembodiment), a lock ring 404 is pressed into the first base ring 402, tolock the housing 104 in place in the wall 106. The lock ring 404 hasbarbs, as shown, threads, hooks, fasteners or other securing mechanismthat mates to the first base ring 402 and/or the second base ring 406.The lock ring 404 could have a front surface flush to the wall 106, witha majority of the lock ring 404 below the surface of the wall 106, orcould have a back surface flush to the wall 106 or recessed slightlyinto the wall 106 and the front surface protruding slightly from thewall 106 or overlapping a portion of the wall 106, in variousembodiments. In further embodiments, the first base ring 402 or thesecond base ring 406 could fix to the wall without need for the lockring 404.

In embodiments with the shaped, reflective rim 210 it is desired thatthe rotatable front screen 202 be nearly flush with the top surface ofthe lock ring 404 and/or the front surface of the wall 106 for aestheticpurposes, although further embodiments could extend further from thewall 106. For example, the height of the shaped, reflective rim 210could be as small as about one millimeter or as great as about one inch,although other dimensions could be used. A portion of the reflective rim210 could be sunken below the front surface of the wall 106 in someembodiments. Reflective rim 210 is depicted having an arc shape in someembodiments but this is not meant to be limiting as alternative shapesfor the outer edge of the reflective rim may be integrated with theembodiments. In some embodiments, an encoder ring having metal lines orlaser etched lines disposed on a surface may be utilized to allow asensor to detect rotation of the rotatable front screen. The encoderring may be integrated with one of the rings described above or may be aseparate ring of the wall controller. The wall controller may alsoinclude a heat sink disposed within the unit to dissipate heat in someembodiments.

FIG. 5 depicts regions of a digital image 510 suitable for projectionfrom the projector 208 in embodiments of the wall controller of FIGS.1-4. Portions of the digital image 510 are circular, to project ontocircular optical components as described above. However, in furtherembodiments, other shapes of these optical components could be used, oroff-axis projection could be used, and this could result in a differentshape for the digital image 510 such as oval for off-axis projectiononto circular optical components, or other geometric shapes. In theembodiment shown, a circular, central region 502 projects onto thebackside of the rear projection screen 204 or the rotatable front screen202, i.e., the rotatable screen 108. A first ring region 504,surrounding the central region 502, projects onto the light pipe 410 toilluminate the rim surrounding the rotatable front screen 202, inembodiments that have the light pipe 410. A second ring region 506,surrounding the first ring region 504, projects onto the reflective rim210, in embodiments that have the reflective rim 210. An outer darkfield 508, surrounding the second ring region 506, the first ring region504 and the central region 502 is black or dark (e.g., the lowest valuefor each of the red, green and blue components in the pixel values) sothat stray light from the image does not bounce around the housing 104and the image does not need physical masking. In further embodiments,masking is added to avoid internal reflections of residual light, sincethe darkest level available from a specific projector 208 may not equateto a total absence of light. Variations on the digital image 510, withadditional regions, combined or overlapping regions, spaces between theregions, or fewer regions, are readily devised. One or more furtherregions could be added around the second ring region 506, for example toproject straight out of the wall interface and onto other elements inthe environment such as an opposite wall. Or, one or more furtherregions could be defined within one of the regions 502, 504, 506,corresponding to a transparent region in the rear projection screen 204and rotatable front screen 202, for projecting onto other elements inthe environment. Each of these regions 502, 504, 506 and/or furtherregions could be provided with an image independent of the otherregions, or these could be coordinated, for various effects. Forexample, the central region 502 could have a message or index markings,or an animation corresponding to perceived rotation of the rotatablefront screen 202 or corresponding to action on a device or system beingcontrolled by the wall controller 102. The first ring region 504 or thesecond ring region 506 could be animated, to show perceived rotation ofthe rotatable front screen 202 or action on a device or system. Thefirst ring region 504 could have a constant or changing color orintensity, for example pulsating or blending from one color to another,or could have sections or segments that are stationary or move. The samefunctionality could be achieved with the second ring region 506,coordinated with or independent of the first ring region 504, or thecentral region 502. A clock could be implemented with hands on one ormore of the regions 506, 504, 502. Indoor or outdoor temperature couldbe indicated similarly, as could other weather information, for examplewith a combination of symbols, words or animation. Night and day, phasesof the moon, seasonal displays, photographic images or movie or videoimages (still or moving), abstract art, etc., are all candidates fordisplay using one or more of the regions 502, 504, 506 of the digitalimage and corresponding display on the rotatable screen 108, the glowingrim or projection surrounding the rotatable screen 108, and the glow 116or projection projected onto the wall 106 or other portion of theenvironment. Embodiments could react to sound or music, or size,movement, proximity or changing distance of a user, for example by beingdark in a quiescent state but waking up or increasing in glow orbrightness as a user approaches, with appropriate sensor(s) in this oranother system to which the window controller 102 is connected andcommunicates.

FIG. 6 is a perspective view of a brake for stopping, slowing,countering or otherwise resisting rotation of the rotatable front screen202 of FIGS. 1, 2 and 4. There are many ways a brake could beimplemented, such as a drum brake, a disk brake, a stepper motoroperated in reverse, a band brake, a clamp, etc. In addition, there aremany mechanisms for the brake to be attached to or interact with therotatable front screen 202, such as directly, or through a rim, a shaft,gears, a region of a surface, etc. In the embodiment shown, a solenoid602 has a plunger 604 which is electromagnetically activated (e.g., bythe controller 234) to press against the cylindrical rim 414 of thefront screen 202, slowing and stopping rotation of the rotatable frontscreen 202. Variations, in which the plunger 604 presses or pullselsewhere, and further embodiments as described above, e.g., to slowdown, increase or decrease friction and resistance to rotation, arereadily devised in keeping with the teachings herein. Some embodimentscould be operated under computer control, others could be directlyreactive to a switch, e.g., a capacitive switch, or other sensingdevice, or a circuit coupled to the capacitive sensing film 408, etc. Insome embodiments a magnet may be utilized as an eddy current break wherean electrical break is created by a magnetic field to slow the metalring without physically contacting the ring. The amount of slowing maybe proportional or inversely proportional to an amount of currentsensed.

FIG. 7 is a perspective view of a tool for installing an embodiment ofthe wall controller 102. The tool has a shortened cylinder body 1002,with teeth 1004. When the tool is rotated on a wall (e.g., by hand or byan electric motor-equipped tool such as a drill), the teeth 1004 cut acircular hole in the wall 106. In some embodiments, the tool or aportion of the tool is left in the wall, and becomes a base ring throughwhich the housing 104 of the wall controller 102 is inserted. The tool,as a base ring, then retains the housing 104 to the wall 106. Retentioncould be accomplished using a fastening or latching mechanism, adhesive,or one or more trim pieces as described above.

FIG. 8A depicts an embodiment of a dynamic user control system for smartdevices including a number of varied user input devices, one of whichmay be the wall controller 102 according to embodiments describedherein. The wall controller 102 and one or more input or I/O(input/output) devices 808 interact with each other and/or interact withone or more smart devices, in this example a smart window 802. The smartwindow 802 has an electrochromic window 804 with controllable lighttransmissivity, and in some embodiments an indicator 806, for exampleattached to the electrochromic window 804, or attached to or integratedwith a frame of the smart window 802. The indicator 806 could be aliquid crystal display (LCD) or one or more LEDs (light emitting diodes)such as an organic light emitting diode (OLED), etc., and could indicaterelative transmissivity of the electrochromic window 804, or changes tothe transmissivity of the electrochromic window, etc. Various input orI/O devices 808 are illustrated, and further input or I/O devices couldalso be used for input to or control of smart devices. A wall switchsuch as slider 810 could be implemented with an elongated touchpad, or aslidable knob with encoding, sensing or other input device coupled tothe slidable knob. The wall switch may have a tactile keypad. In someembodiments, the wall switch could have an output device such as aliquid crystal display, or multiple LEDs, perhaps even three color orRGB (red green blue) LEDs. The wall switch 810 could be mounted, e.g.,on a wall, or portable, as a remote control, and could have one or morebuttons or keys in various embodiments. In one embodiment the wallswitch 810 may be a toggle or bar with buttons on either end of the barto allow a user to change the tint level of an electrochromic smartdevice. As illustrated, a slider 810 may have a portion mounted to awall and a portion slidably affixed to the portion mounted to the wallto enable access to batteries, among other items. A keypad 812 could bemounted, e.g., to a wall, or portable, and include multiple buttons orkeys, which could be physical devices or regions of a touchpad. Atouchpad 814 could be mounted, e.g., to a wall, or portable, and able tosense one or more fingers. Touchpads are available with display output,e.g., LCD displays, or other types of LED displays. A smartphone 816 orother mobile device could have one or more applications or “apps” andserve as a user input or I/O device. Smart wearables 818 may also serveas a user input device, such as a watch, a collar, a badge, a key fob,ear attachable devices, etc., may have Bluetooth™ connectivity. A tablet822, with computer and touchscreen capabilities, could have one or moreapplications or “apps” to serve as an input or I/O device. Similarly, apersonal computer 824 (e.g., a tower, laptop, notebook, etc.) could haveone or more applications to serve as an input or I/O device. User inputdevices such as the smartphone 816, the smart wearables 818, the tablet822, or the personal computer 824 may provide passive or active userinput to the dynamic user control system. For example the occupancy of aspace may be determined by the detected presence of such a user inputdevice. Any of the above could have wireless connectivity andcommunicate as depicted in FIG. 9. In some embodiments the wirelessconnectivity may be provided by a wireless mesh network using a protocolsuch as Zigbee or Thread. Also, voice control 820 could be used, forexample with a user speaking to one of the user input or I/O devices 808that has a microphone and speech recognition capabilities. In someembodiments, the wall switch or wall controller is capable of receivingan audio command, such as voice commands form a user either direct orthrough an intelligent personal assistant or intelligent home controldevice, and distribute instructions based on the received audio commandto another controllers or an electrochromic device. Light sensors,temperature sensors, motion sensor, occupancy sensor, intelligentpersonal assistants, any other intelligent home control device,including an Internet of things (TOT) device or intelligent lightingsystems, etc., may be integrated with the embodiments and included as anI/O device 808. The I/O devices 808 can include sensors on laptops orother portable/mobile computing devices. In some embodiments, the windowmay be controlled by touching the window itself for input. FIGS. 8B and8C illustrate an example slider controller 810 that can communicate withthe wall controller in accordance with some embodiments. Slidercontroller 810 may communicate with the electrical drivers for one or aportion of the electrochromic doors or windows in the system. FIGS. 8Band 8C are not meant to be limiting as any of the user input devices 808or I/O devices may communicate directly with the electrical driversusing either wireless or wired connections. In some embodiments the userinput devices 808 or I/O devices may communicate with the electricaldrivers over a local area network or a local mesh network. In otherembodiments the user input devices 808 or I/O devices may communicatewith the electrical driver though the internet or a cloud, where therouting of the communications through the cloud is performed by anetwork gateway device local to the dynamic user control system and thesmart windows as will be described below in reference to FIG. 9.

FIG. 9 depicts an embodiment of an overall control system for smartdevices, such as smart windows 802, which receives user input from, andcommunicates with, a dynamic user input control system. Input or I/Odevices 808 are represented in the diagram as having wirelessconnectivity through an antenna 904. Multiple controllers 914 are shownin various devices and FIG. 9, and could singly or in cooperationcontrol smart devices, in a distributed control system or a hierarchicalcontrol system, or a hybrid combination of these. Here, the smartdevices are smart windows 802, each of which has an antenna 904 and acontroller 914, although some embodiments omit the controller 914. Thesesmart windows may incorporate electrochromic devices. The wallcontroller 102 could be any of the embodiments described herein, andcould have a controller 914 and an antenna 904. In some embodiments, acontroller 914 in a smart window driver 912 directs voltage and currentlevels for the smart windows to change transmissivity of theelectrochromic window 804 (see FIG. 8A), and in other embodiments, thesefunctions are controlled by a controller 914 integrated in or externalto the smart window 802. Further information on the smart window drivermay be found in application Ser. No. 14/994,091, which is incorporatedby reference for all purposes. A network gateway device 902, also with acontroller 914 and an antenna 904, communicates with any of theabove-described devices, and serves as a gateway to a network 906, suchas the global communication network known as the Internet, or anintranet or a cloud network. As part of the network 906, smart windowservices 908 (which could be implemented using one or more servers)includes a controller 914, scheduling 916, device statistics 918, sitedata 920, an application programming interface (API) 922, a buildingmanagement application programming interface 924 and/or other cloudservices for the smart windows 802 or other smart devices, in variousembodiments. External cloud services 910 are also connected to thenetwork 906, and could provide information for use by the variouscontrollers 914 in controlling the smart devices, such as the smartwindows 802 in this embodiment. In some embodiments controller 914 maybe embodied as a slider controller 810 as mentioned herein and cancontrol a window/door or a group of windows/doors. Controllers 914 maycommunicate through a mesh network (utilizing a protocol such as Zigbeeor Thread) and take over control of the smart windows or doors in thecase of loss of communication with the gateway 902 or loss ofconnectivity between the gateway 902 and network 906. In someembodiments, a mesh network that is Internet protocol (IP) based enablesa border router in the gateway to allow access and/or control of thesmart window or door drivers or controllers to any IP based device onthe mesh network. Further embodiments with various combinations ofwireless and wired connections are readily devised as variations.

As one example, a specified smart window or door 802, a group of smartwindows or doors 802, or all of the smart windows and doors 802 in aspecified installation could respond to whichever of the input or I/Odevices 808, the wall controller 102, the network gateway device 902, orthe smart window services 908 is actively directing transmissivitycontrol of one or more smart windows 802 at a given moment. Inhierarchical systems, various levels of control within the system couldhave specified priorities, and override other levels. A heuristicembodiment could learn from conditions and user inputs, and developcontrol schemes, user preferences, etc. Hierarchical organization andpriorities could be changed over time as a result of system learning, orestablished by a user, or a combination of these.

As another example, each room or group of smart windows 802 could beassociated to a user input or I/O device 808, or a wall controller 102,or wall switch, for that room, group or a user, and that device couldact comparably to a light switch. Another controller 914, such as one inthe network gateway device 902, or perhaps the wall controller 102 forgroups of smart windows 802, could handle overall control of the smartwindows 802. In a large commercial building, a building managementsystem (BMS) could have priority over other user inputs to maintainoptimal energy profile for the building. Priority for input or I/Odevices 808 or the wall controller 102 could be based on which inputdevice a specified user uses most frequently, and this information couldbe collected in the smart window services 908 in the network 906 andanalyzed to establish and adjust over time.

Further embodiments of the wall controller and/or the control system forsmart devices are envisioned for automotive use. For example, the wallcontroller could be mounted to a wall of an automotive door or dashboardpanel, a wall of a roof liner, a wall of an automotive compartment, etc.The control system could interact with smart devices for control ofsmart electrochromic windows in the automobile, or other smart devices.The term “wall”, relative to embodiments of the wall controller andmounting thereof may be interpreted broadly as pertaining to variousstructures of buildings and vehicles including compartments, partitions,loadbearing and non-loadbearing walls, ceilings, floors, separators,dividers, panels, doors, and other structures to which a controllercould be mounted, etc.

In FIG. 10A the wall controller 102 is illustrated asdescribed herein. Wall controller 102 may control the smart windows anddoors for an entire home or business or a portion or groups of windowsand doors. In FIG. 10B a mobile computing device 1002 is utilized tointerface with individual smart windows or groups of smart windowsthrough an application or “app” executed on the mobile device. Asdiscussed below in FIGS. 13A-E, the application may be utilized tocreate and edit scenes or change settings. FIG. 10C illustrates acontroller 810 which in this embodiment is illustrated as a slider wallswitch that may be utilized to control a smart window or door or a groupof smart windows or doors. The controller 810 may be any of the userinput devices described herein. Controller 810 may be able tocommunicate with other controllers 810 that control other windows anddoors or a group of other windows and doors. The communication may beachieved through a mesh network which may utilize a protocol such asZigbee or Thread, an Internet protocol based network communication, orany other suitable wireless network. In some embodiments, thecommunication between the various nodes through slider controller 810,also referred to as a wall switch, in a peer to peer type configurationwill enable continuity of service where the gateway is down andcommunication may be lost through the cloud interface. In someembodiment, the controllers on the peer to peer network can execute thelast known schedule delivered through the gateway prior to loss ofcommunication or connectivity with the cloud. The communication throughthe mesh network in a peer to peer network may override control of thesmart windows and doors in some embodiments.

In the illustrated flow a user may click on a room or fullhome and then select a scene for the room or home to be applied to thatroom or the full home. In the example flow the user has selected tocontrol the electrochromic windows according to a scene for the kitchen.Examples for setting up a scene and editing or adding scenes or windowsare illustrated in FIGS. 12A-12E. In FIG. 12A a user interface for ahome page on a controller or slider controller unit is provided. FIG.12B illustrates a user interface for adding a new space while FIG. 12Cillustrates a user interface for creating a new scene. FIG. 12Dillustrates a user interface for selecting windows in a scene, whileFIG. 12E illustrates a user interface for editing a scene.
